IMPROVEMENT IN HARROWS. d

. ---o-4. The Schedulo'xeferred to in these' Letters Patent and maldng part of the same.

To all whom z't ma/yconcern.- "r

Be it known that'I, ANDREW A. NUQUIBT, of Oneida, in' the county of Knox, and in the State 'of Illinois, have inventedcertain new and -useful Improvements in Harrows; and do hereby declare that the following is a full, clear, and exact description thereof,

I will 'now proceed to deslibe its construction and` operation, referring to the annexed drawings,whioh form a part of this specification, and in which- Figure 1 is a plain view, and

Figure 2 a side view. 'Figure-Sis a plan of the evener, used when the 'barrow is divided and drawn by one 'horse only.

My harrow;consists of two single harrows, each made of several series of bars, A A, BB, and C O, placedin zigzag form, end to end, with cross-bars D D placed on top, and the Whole connected and held together by means of the barrow-teeth 1lv E, which are, on their upper ends, provided'with screw-threads.

The'screw-ends of the teeth A A pass through the bars andAcross-bars, and nuts, F F, are placed ou the same, thus holdingall the part-s of the single harrow together. 1

The cross-bars D, next to the last, at each .end are connected by a metal bar, G, as shown in iig. 1, and across the two cross-bars, at the front of the barrow,

.are two other metal bars, H H, all of which metal bars are secured by being put on the "screw-ends of some of `the teeth before their nuts are screwed ou.

The metal barsH H extend a suitable distance in fzont of the harrow, and are,lby means of hooks I I,

zharrow," which will' connecte-d with a ba'r, K, to which the team is hitched iu any suitable'manner. f A

The inner ends of the rear cross-bars D, of thetwo single harrowsare connected by means ofl a hook, L. When it is *desired to'use one of the harrows alone, they can easily be unhooked from eachother, and from the-.bar K, and one of them hooked to a. smaller evener, J, suitable for one horse. v y

. The 'advantages that Ifconsider this barrow to pos" sess over all others now in'usearamainly', that' the .teeth or tines are so far apart as to clear themselves in cornstalks, sodded ground, lor `in anylother place where other harrows are liable to clog; that the joint or link between the two harrows will allow it to coverseed in all places where a dead furrow o'r un'even ground may be found; that the harrows take a full stroke and complete the work as they go; that they can be easily .taken apart, and one horse-canV do the work in or.- lchards and other places Where a full barrow Ycannot be used; that tliebars, of which, the harrow is con structed, can be made of boards, which is agreat object- `in so'me places, wherescalntlings or beams are so asvnot to be liable to get lost, and, at the same time, serve 'as bolts tofhold the wood-work together.'

I am aware that a zigzag harrow is not new; also,

draught-bar are known,

W'hat I claim, is-

A double zigzag barrow formed of a series of separate bars A B C D, 'iiatbraces G H, and teeth E, secured by nuts F through thezigzag and cross-bars, all constructed and arranged substantially as set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 25th day of Nove1nber,.1'868.
